Hey peeps - I've got a multi camera GH5 and GH5s (one of each) project coming up with a Ninja Inferno attached to the GH5s. I'm wondering how best/most easily to make sure all three are timecode-synced for the duration of the shoot with a minimum of fuss and no additional gear.

All ideas/suggestions welcome. Thanks!

The GH5s has an issue with its timecode port which causes timecode to drift immediately upon input. I don't know if it does timecode out, but if it does, then the best idea is to use the Inferno with the GH5, and connect the GH5s cable (if it has a BNC end and does LTC out) to the Inferno on the GH5. Then you'll have to record on the Inferno, and the ProRes files should have matching timecode.

Your other options are Tentacle Sync hardware, PluralEyes, or the built-in sync functionality of Premiere/FCPX (not sure about other NLEs).
